Hand‐written fabrication techniques offer new ways of developing customizable, biodegradable, and low‐cost electronic systems. In this work, a new level of complexity is demonstrated for hand‐written electronics by fabricating passive components, circuits, and a sensor system on paper. The system comprises a pencil‐written graphite force‐sensitive resistor, a pencil‐drawn RC filter, a pen‐written half‐wave rectifier, and a commercial front‐end voltage amplifier. The sensor system exhibits a linear response for pressures up to 1.2 kPa, and a sensitivity of 51 mV kPa⁻¹. Furthermore, the electrical and mechanical performance of the single components and circuits is studied. Diodes fabricated through pen‐written deposition of silver and nickel contacts on amorphous indium–gallium–zinc oxide coated paper show rectification ratios up to 1:8. Tensile and compressive bending measurements applied to all pencil‐written components for radii down to 0.1 mm indicate minor influence of strain. Similar results are obtained for circuits created from these individual components. Diodes and half‐wave rectifiers show a stable behavior when bent to a radius of 5 mm. The presented techniques can enable the development of flexible and eco‐friendly wearables and sensors for consumer and healthcare applications, and are an effective way for school pupils to explore the world of electronics.

纸上压力传感器系统的手绘电阻器，电容器，二极管和电路

手写制造技术提供了开发可定制，可生物降解和低成本电子系统的新方法。在这项工作中，通过在纸上制造无源组件，电路和传感器系统，展示了手写电子设备复杂性的新高度。该系统包括一个铅笔写的石墨力敏电阻器，一个铅笔绘制的RC滤波器，一个笔写的半波整流器和一个商用前端电压放大器。传感器系统在压力高达1.2 kPa时表现出线性响应，灵敏度为51 mV kPa ^-1。此外，还研究了单个组件和电路的电气和机械性能。通过在非晶态铟-镓-氧化锌涂层纸上手写沉积银和镍触点制成的二极管，其整流比高达1：8。对半径小于0.1 mm的所有铅笔书写组件进行的拉伸和压缩弯曲测量表明，应变的影响较小。对于由这些单个组件创建的电路，可获得类似的结果。二极管和半波整流器在弯曲到5 mm的半径时表现出稳定的性能。所介绍的技术可以为消费者和医疗保健应用开发灵活，环保的可穿戴设备和传感器，并且是在校学生探索电子世界的有效途径。
